Abstract (en)
[origin: EP0788873A1] A process for producing a multilayer elastic sheet from at least one elastic rubber layer (10) of film, foil or fibrous structure and at least one reinforced inelastic nonwoven fleecy layer (12) joined to the first layer at permanent bonding points (16) entails pre-stretching the fleecy layer so its fibres (18) are aligned in the pre-stretch direction and attaching it to the rubber layer in the pre-stretched state. Also claimed is the multilayer sheet obtained per se. The sheet can be reversibly stretched in a direction transverse to the pre-stretching so that the fibres of the inelastic fleecy layer between the attachment points alter their orientation to that of the stretch depending on the degree of stretch.
